The correlation coefficient r between the number of hours spent by the learners in studying and their academic performance was found to be 0.97. Based on the finding, which of the following best describe the result?

a.

There is a strong positive correlation between the number of hours spent by the learners in studying and their academic performance. As a learner spends more time in studying, the higher is their academic performance.

b.

There is a strong negative correlation between the number of hours spent by the learners in studying and their academic performance. As a learner spends more time in studying, the lower is their academic performance.

c.

There is a perfect correlation between the number of hours spent by the learners in studying and their academic performance. As a learner spends more time in studying, the higher is their academic performance.

d.

There is no correlation between the number of hours spent by the learners in studying and their academic performance.
